Laravel 8 Error Cors

I have an Api Rest with Laravel 8 and a front-end with VueJS, everything works fine from postman, but when making requests from Vue it gives cors error.

I also tried creating a Cors middleware that contains the following:

    public function handle(Request $request, Closure $next)
    {
        return $next($request)->header('Access-Control-Allow-Origin', '*')
        ->header('Access-Control-Allow-Methods','GET', 'POST', 'PUT', 'PATCH', 'DELETE', 'OPTIONS')
        ->header('Access-Control-Allow-Headers', 'Content-Type, Authorization');
    }

It also keeps throwing cors error, the library that includes the laravel version is: "fruitcake / laravel-cors": "^ 2.0", but this still doesn't work.

How could I fix my cors error?

I have same problem. If you upgrade Laravel version, then it is over.

I was able to solve the problem in this way, in my case it was due to a configuration that needed the web.config file, I had to add the following

    <httpProtocol>
      <customHeaders>
        <add name="Access-Control-Allow-Origin" value="*" />
        <add name="Access-Control-Allow-Methods" value="*" />
        <add name="Access-Control-Allow-Headers" value="Access-Control-Allow-Headers, Origin,Accept, X-Requested-With, Content-Type, Access-Control-Request-Method, Access-Control-Request-Headers, Authorization" />
      </customHeaders>
    </httpProtocol>

And my file stayed like this

<configuration>
  <system.webServer>
    <rewrite>
      <rules>
        <rule name="Imported Rule 1" stopProcessing="true">
          <match url="^(.*)/$" ignoreCase="false" />
          <conditions>
            <add input="{REQUEST_FILENAME}" matchType="IsDirectory" ignoreCase="false" negate="true" />
          </conditions>
          <action type="Redirect" redirectType="Permanent" url="/{R:1}" />
        </rule>
        <rule name="Imported Rule 2" stopProcessing="true">
          <match url="^" ignoreCase="false" />
          <conditions>
            <add input="{REQUEST_FILENAME}" matchType="IsDirectory" ignoreCase="false" negate="true" />
            <add input="{REQUEST_FILENAME}" matchType="IsFile" ignoreCase="false" negate="true" />
          </conditions>
          <action type="Rewrite" url="index.php" />
        </rule>
      </rules>
    </rewrite>
    <httpProtocol>
      <customHeaders>
        <add name="Access-Control-Allow-Origin" value="*" />
        <add name="Access-Control-Allow-Methods" value="*" />
        <add name="Access-Control-Allow-Headers" value="Access-Control-Allow-Headers, Origin,Accept, X-Requested-With, Content-Type, Access-Control-Request-Method, Access-Control-Request-Headers, Authorization" />
      </customHeaders>
    </httpProtocol>
  </system.webServer>
</configuration>

This alone still gives a Cors error, but it is due to the implementation of the fruitcake that the laravel version already brings, it is only necessary to comment that class in the kernel

    protected $middleware = [
        \App\Http\Middleware\TrustProxies::class,
        // \Fruitcake\Cors\HandleCors::class,
        \App\Http\Middleware\PreventRequestsDuringMaintenance::class,
        \Illuminate\Foundation\Http\Middleware\ValidatePostSize::class,
        \App\Http\Middleware\TrimStrings::class,
        \Illuminate\Foundation\Http\Middleware\ConvertEmptyStringsToNull::class
    ];

Now with this it works fine
